GALLI GAN, OF BRIDGEPORT, CONNECTICUT,ASSIGNOR TO THE IVES CORPO- I RATION, OF BRIDGEPORT, OONNEOTICUT ACORPORATION OF CONNECTICUT TOY LOGOMOTIVE WHEEL Application filed March8,

This invention relates to improvements in flanged wheels for toylocomotives and cars, particularly adapted for use on six wheel truckssuch as are used on toy railway trains and more particularly locomotivesfor pcrating such trains and especially refers to a novel form offlanged wheel to be used as a driving wheel on locomotive trucks so thatthe same will more freely run over curved sections of track Withoutbinding and retarding the speed of the train.

In the past it has been more or less im practicableto operate a sixwheel type of locomotive upon the commercial sectional types of toytracks including curved sections, particularly where such driving Wheelswere connected with side bars and linkage, for the reason that the threewheels on each side were in alignment one with the other on a truckframe which did not permit of sidewiso movement of the wheels and thuscould not conform with the radiusof the curved track sections in a wayto permit the truck to take the curve. I-Ieretofore various and more orless impracticable means have been devised for accomplishing thispurpose, in some instances extra play to permit longitudinal movement ofthe center axle has been provided but this was not practical because theposition of the side bars on each side would not allow the center pairof wheels and axle to shift longitudinally of their axis sufliciently topermit the truck to run over curved sections. In other instances centerdriving wheels have been employed which had no flanges and whichobviously permitted the truck to run around the curve without frictionor resistance but in this latter case the center wheel was different inappearance from the others which detracted materially from the design ofthe locomotive.

I have therefore devised a form of wheel and truck whereby a six wheeltype of truck may be built and applied to a toy locomotive,

which will freely run over the present commercial curved type of trackwithout undue friction and in a way to permit of the use of side barsand links upon the outside of the be. driving wheels as is the presentcustom;

1928. Serial No. 259,995.

In the production of a six wheel truck of this type I find it isnecessary to use but two of the improvedtype of wheels, one on each sideand both preferably in the center. of the truck, using the old form offlanged driving wheels on each end of the truck, or front and rear ofthe new type of flanged driving wheels.

Other objects are compactness, accessibility and freedom from parts ormechanisms which will readily go out of order.

With the above and other objects in view an embodiment of the inventionis shown in the accompanying drawings and this embodiment will behereinafter more fully described with reference thereto, and theinvention will be finally pointed out in the claims.

In the drawings: 7

Fig. 1 shows a side elevation of a commer cial steam type of electrictoy locomotive and to which my invention is adapted to be applied; r

Fig. Qshows a detached plan view of a locomotive truck, as employed onthe type of engine shown inFig. 1, and embodying six driving wheelsmounted upon a curved section of toy electric third rail track;

Fig. 3 is a vertical cross section through truck frame, axle and drivingwheels, taken on line 33 of Fig. 2;

Fig. 4 is a sectional elevation taken on line 4-4 of Fig. 2, showing thecenter driving wheels as they would appear when mounted upon a straighttrack section; and

Fig. 5 shows a detached perspective view of a modified form of spring tobe used in holding the separable flange of the driving wheels inposition.

Referring in detail to the characters of reference marked upon thedrawings, 6 represents a commercial steam type of toy locomotive towhich my invention is adapted to be applied. This locomotive may beconstructed in whole or inpart of cast iron and while designed tobeoperated by electricity taken from a third rail, yet it is alsoadapted to be operated by a spring movement, not shown, when substitutedfor an electric movement that may also be contained in the truck framemounted in the body of the locomotive. i

7 represents the truck frame which is secured within the cast shell ofthe locomotive by means of screws 8, or other suitable means, not shown.These movements when made up to be operated by either spring or electricmotor usually comprise side plates 9+9 which are secured together and inspaced relation by means of rods 10, the ends of which extend thpegghthe frame plates and are riveted upon the so as to form a rigid frame.

The axles 11 l1 may be of the usual construction formed of wire androtatably mounted in the side plates 99 of the frame and serve toreceive flanged driving pulleys 12 secured thereto, one on each end ofthe axles and in proper s aced relation one to the other according tothe particular auge of thetrack and size of the locomotive. hese axlesmay he further provided with gears 13 to connect with the 0 teratingunit, not shown, for the purpose 0 driving the locomotive. The centeraxle 14 is also journaled in theside lates of the frame and is free toturn wi the rotation of the connected wheels 15 mounted thereon.

These wheels 15 operatively speaking, are more in the nature of idlersthan drivers for in ractise they are not usually directly conne ed tothe motor. They are however 0 ratively connected to the end driving eelsthrou the side bars 16 and also connected by the links 17 with thepiston slide 18, see F1 l. The center wheels 15 are prointegral hubportions 19 w ich bear against the outer face of the plates 9 but arenot provided with an integral annular flange around their inner edgeportion, as is customarily the case with locomotive and car wheels, butare rovided with a movable flange 20 which is ormed of the outer edge orrun port-ion of a flat disc '21 which is slidably fitted upon the hub 19of the wheel. These flanges, see '3, are normally pressed outward bymeans of a spring '22'niounted u on the hub 19 of the wheel in a mannerto ylieldabjly hold the flanged disc out against the inner face of'thewheel and to permit them to move in upon the hub against the action ofthe sprin when the flange crowds against the inner. ace of the innerrailof a curved track section as is demonstrated at inFi .2and'3.

In E ig. 5 I have shown a flat sheet metal sprin 22 which maybe usedupon the hubs 19 in place of the coiled spring to hold the flanges outagainst the inner face of the wheels 15. 7

These curved sections in the track are the points in the track, with theo ration of the old formsof trucks, where friction occurred since it wasimpossible for the three aligned integrally flanged wheels on each sideto take the curve, as is done with the movable form of flanges asprovided in disclosed.

my invention herein Having thus described my invention, what I claim anddesire to secure by Letters Patent is 1. In a toy railway car Wheel, atruck frame, an axle mounted therein, wheels secured to the axle, discsmovably fitted against the side of the wheels and having annular flangeportions extended beyond the periphery ,of the wheels, and springsinterposed between the frame and the flanges to yieldably hold thelatter against the sides of the Wheels- 2. In a toy railway car wheel, atruck frame, an axle mounted thereon, wheels secured to the axle, discsmovably fitted against the inner side of the wheels and having annularflange portions extended beyond the periphery of the wheels, and springsinterposed between the frame and the flanges to yieldably hold thelatter against the sides of the wheels.

3. In a toy railway car wheel, the combination with a truck frame, anaxle mounted therein, wheels mounted on opposite end portions of theaxle and having inwardly extended hub portions, movable disc flangesmounted on said hubs adjacent the inner sides of the wheels, and meansfor normally holding the disc flanges against the side of the wheels.

a. In a toy railway car truck, the combination with a truck frame, aseries of axles mounted therein, plain and flanged wheels mounted on theaxles, the plain wheels having inwardly extended hub portions, movabledisc flanges mounted on said hubs adjacent the inner sides of thewheels, and means for normally holding the disc flanges against the sideof the wheels.

5. In a toy railway car truck, the combination with a truck frame, aseries of three axles mounted therein, flanged wheels mounted on some ofthe axles, and plain-faced wheels mounted on another of said axles, a

movable flange mounted adjacent the inner Fa rdeld and State ofConnecticut, this 7th day of March, A. D. 1928.
